Confirming 302 Head Exhaust Valve Rotator Removal Parts

PRH said
When I have eliminated the rotators on Mopar heads, I swap all the associated parts to the Non-rotator pieces.
Valves/retainers/locks.

The valves and locks for the non-rotator applications are 4 groove instead of 2.

You may be able to reuse the valves and locks if the installed height is sufficient.

Aha, so that explains why the locks that came with my camshaft were 4 groove (all the valves in my 302 heads are 2 groove). If I get exhaust valves for 1970s 318 heads then will that work? I believe rotators didn't come out until later. Anyone have a recommended source for such exhaust valves?
